Vegan Options at Burger King (US, UK and Ireland)

By PhilippeIngredient checks · Updated Oct 2026 Reviewed Oct 2026 · US, UK and Irish menus
THE VERDICTYes, with one swap

Burger King is one of the better burger chains for vegans. In the US, order the Impossible Whopper with no mayo and add fries; at breakfast, the French toast sticks and hash browns are vegan. In the UK, the Plant-Based Whopper and Vegan Royale are vegan as served.

Plant-based patties are cooked on the same broiler as beef unless you ask otherwise.

Burger King was the first big US burger chain to put a plant-based burger on its permanent menu, and it's still the easiest burger chain for a vegan meal. In the US you need to make one change to the burger. In the UK, the vegan burgers are ready to order as they come.

How to order the Impossible Whopper vegan

  1. Order an Impossible Whopper, no mayo.
  2. Add mustard or extra ketchup if you want something saucy.
  3. If you don't want it cooked alongside beef, ask for it to be prepared without the broiler. Burger King cooks the Impossible patty on the same broiler as beef by default.
  4. Add classic fries.

In the app, open the Impossible Whopper, remove the mayo under "customize", and add the preparation note if the option is offered. The app is the easiest way to make sure the change goes through.

Breakfast

Before 10:30 a.m. most US locations serve French toast sticks and hash browns, both vegan as served. Coffee is black only, since Burger King doesn't usually stock plant milk.

Burger King in the UK and Ireland

Cross-contact

Burger King cooks plant-based patties on the same broiler as beef unless you ask otherwise, and fryers are shared. That doesn't change the ingredients, but it matters if you avoid any contact with meat or have an allergy.
